I think I can say it was a true labor of love from everyone in the team. I remember having been contacted by Kyence 4 years ago! Hiei- joined then for working on the French translation, then the English one. Everyone worked very hard, despite real-life constraints.
I hope it'll help to prevent this great game from the beginning of the 16bits era to fall into oblivion. Yes, it's hard as hell, but the story is rewarding!
